Chiefly in British English: Masturbating with a condom on.
She flaked last minute so I ended up having a posh wank instead.

Get the Posh wank mug.
When you take time to set the scene before masturbating.
Arrange the sofa cushions, dim the lights, maybe put on some soft music (as long as it's not Chris De Burg) and pour a large glass of red wine - (probably not new world).

For added poshness, choose some porn that doesn't make you feel sickened the moment you've shot your load onto the balsam tissues.
My wife's away, so I'm going to take my time and stay in for a posh wank this evening.

A posh wank is slang for a wanker who is wanking with a condom on. Whilst the condom itself does not make the wank posh. The wanker may raise their pinky finger whilst wanking therefor making it a posh wank. To make a posh wank more posh the wanker may drink some tea whilst wanking or the wanker may wear a top hat and monicle. Therefore making the wank more posh.

When you jerk it with your pinkie up - like a Victorian era gentleman drinking a cup of tea.
I was so ready for an upper-class experience I had to pre-empt it with a posh wank

To masturbate wearing an opened plastic sandwich bag instead of condom. Hence, no messy clean up and less expensive especially with coupons and sales.
Money is tight right now so I had to ghetto posh wank instead of buying condoms.

When a woman gets all dressed up, posh underwear, heels, the lot...then masturbates while slowly turning herself on by looking so bloody fantastic!
